QuestionAnswer
what is a wave a disterbance that transfer energy
what is a medium the meterial solid liquid or gas through which a wave can travel
what is a transverse wave when particles move perpendicularly to the direction the waves travel
which part of the wave is the crest the highest part of the wave
which part of the wave is the trough the lowest part of the wave
what is a longitudinal wave when the particles move back and forth
which part of the wave is the compression the strongest part of the wave
which part of the wave is the rarefaction the weakest part of the wave
what is a mechanical wave waves that require a medium
what is a electromagnetic wave a wave that does not require a medium
what is amplitude a measure of how far apart the particles are in a medium
what is wave length the length of the wave
what is frequency the amount of speed in a wave
what is hertz how you measure a wave
what is wave speed the speed of the wave
what is force a push or a pull exerted on an object in order to change the motion of the object
what is work the use of fore to move an object some distance
what is power the rate of how much work is done
a 100n girl climbs a flight of stairs in 5 seconds. The stairs are 5m high, how much power did she generate? 100watts
a force of 40 newtons pushing an object 10 meters in the direction of the force the force does 400 newton meters
the frequency of a wave was 60 hertz and the wavelength was 10 cm find its speed 600 cm/sec
what type of waves dont need a medium electromagnetic waves
in a longitudinal/transverse wave particles move at right angles to the direction the wave travels transverse wave
how do you calculate speed distance divided by time
as the frequency increases the wavelength decreases
what is rest position when the particles are in a displacement
how do you calculate power work divided by time
